Step-by-step troubleshooting guide for Galaxy S8+ with black screen of death

Problem: My phone won’t respond anymore. It’s still a few weeks with me and I bought it brand new but it’s screen is always black and it won’t turn on when I press and hold the Power button. I have no idea what happened to it why it’s doing this but I’m very worried since I bought it for several hundred dollars I just can’t afford to have a defective phone right now as I’ve been using it for my email since my laptop broke down. So, if you guys know how to get my phone working again, please help me. It’s the new Galaxy S8+. thank you.

Troubleshooting: The black screen you’re currently experiencing might be just a symptom of a more serious firmware issue but it could also be just a glitch in the system. In this troubleshooting guide, we will try to rule out each possibility and we’ll start from those that are safe to do. We will consider the fact that you may already have some important files or data saved in your phone so it’s always the best option to try to fix the problem without losing those. That said, here’s what I suggest you do:

Step 1: Force Reboot your phone

Usually, for phones with removable battery, you just have to remove the battery to do the forced reboot procedure. However, for the Galaxy S8+ that doesn’t have a user-removable battery, you have to press and hold a combination of buttons to simulate the battery disconnect process. Before I tell you how to do that, this method is actually very effective in addressing this kind of issue that’s caused by minor firmware or hardware glitches. It’s safe to do as nothing will be deleted and changed so this must be the first thing you have to do.

  • Press and hold the Volume Down and the Power keys together for 7 to 10 seconds.

Assuming your phone has enough battery and that the problem isn’t really caused by a serious issue in the firmware, it may restart successfully and this might be the only thing you need to do to fix the problem. However, if it still doesn’t turn on after this, try to do the next step.

Step 2: Charge your phone for 10 minutes

Perhaps, the reason why your phone isn’t turning on is maybe the battery was drained completely and to make things worse, the system may have crashed as there are times when it couldn’t completely power down due to insufficient battery. So, in this step, I want you to try to charge the phone for, at least, 10 minutes. Regardless whether the phone responds when plugged in or not, just leave it connected to its charger for 10 minutes. After which, try to do the forced reboot procedure again to rule out the possibility that the cause of the crash is a drained battery.

If the screen still remains black after this, then try doing the next steps.

Step 3: Attempt to boot in Safe mode

The problem we’re facing is that the phone’s screen remains blank or black no matter what you do. The simple solution is to make the phone power up since we really cannot do some troubleshooting procedures if there’s no power. Therefore, we can make the phone power up in one of the modes, then we can almost say the problem is fixed, although we still have to know what caused it.

In this step, I want you to try booting up your phone in Safe mode. In this environment, all third-party apps are temporarily disabled so if the problem is caused by one or some of those apps, then your phone shouldn’t have any issues booting up in this mode. Here’s how you do it:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Uninstall apps that are causing a problem.

If the phone has successfully started up in this mode, then one or some of the third-party apps installed on your device must be causing the problem. You need to find those apps, try to update and reset them and if that won’t work, then you have to uninstall every app that you think is causing the problem.

How to update apps on your Galaxy S8+

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu > Settings then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

How to clear app cache and data on Galaxy S8+

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display preinstalled apps.
  4. Tap Storage.
  5. Tap Clear data and then tap OK.
  6. Tap Clear cache.

How to uninstall an app from Galaxy S8+

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display preinstalled apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

On the other hand, if the phone still refuses to power up in Safe mode, then the next step might help.

Step 4: Attempt to boot in Recovery mode

Again, we simply want to know if your phone is still capable of powering on because if it can, then, we might be able to fix the problem on our own and you can rest assured that the problem isn’t with the hardware. In this step, you need to try to bring the phone to boot up in Recovery Mode wherein the Android interface isn’t loaded. No matter how serious an issue with the firmware is, there’s still a big chance it can boot up in this mode and if successful, you can actually do a couple of things that might just fix the problem for good and that’s to wipe the cache partition and do the master reset. So, I urge you to try and these procedures.

How to boot in Recovery Mode and wipe cache partition

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe cache partition”
  5. Press Power button to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

How to boot in Recovery Mode and do the Master Reset

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

If the phone still has a black screen after these procedures, then you should bring it back to the store and have it replaced as there’s something wrong with the hardware.
